For the net ionic reaction: 2 Ag+ (aq) + Cu (s) –> 2 Ag (s) + Cu2+ (aq), the number of electrons transferred from Cu (s) to Ag+ (aq) is: 4. For the reaction Zn (s) + CuSO4 (aq) –> ZnSO4 (aq) + Cu (s), the species which is oxidized is: 5. A 0.200 M solution of Pb(NO3)2 (aq) with a volume of 300. 0 mL is mixed with enough NaI (aq), resulting in the formation of PbI2 (s). The molecular equation for this reaction is: Pb(NO3)2 (aq) + 2 NaI (aq) –> PbI2 (s) + 2 NaNO3 (aq). How many grams of PbI2 (s) will precipitate? AgNO3 (silver nitrate) is soluble in water. Which of the following solutions will precipitate silver in the form of an insoluble compound? For the properly balanced chemical equation between sulfuric acid and sodium hydroxide, written as a molecular equation: H2SO4 (aq) + 2 NaOH (aq) –> Na2SO4 (aq) + 2 H2O (l), the spectator ions are: Sulfuric acid (H2SO4) has a maximum molarity of 18.0 M. If we remove 15.0 mL from that concentrated solution, how many moles of H2SO4 are on that volume of solution? A solution of 1.25 M NH3 has an initial volume of 600.0 mL. To that solution, enough water is added, making the final volume 900.0 mL. The molarity of this new solution is: What is the mole fraction of methane on a homogeneous mixture of 40.0 g of CH4 and 40.0 g of O2? A solution is prepared by mixing 200.0 mL of ethanol (C2H6O, density = 0.789 g/mL) with 200.0 mL of water (density = 1.00 g/mL). The molality of this solution is: A solution is prepared by dissolving 10.7 g of NaNO3 in 100.0 mL of water. Assume that the volume of the solution is unchanged by the addition of 10.7 g of NaNO3. The molarity of NaNO3 in this solution is: The correct balanced equation for the reaction between dinitrogen pentoxide and sodium metal to produce sodium nitrate and nitrogen dioxide is: A 2.00 g sample of ammonia is mixed with 4.00 g of oxygen, according to the reaction below. 4 NH3(g) + 5 O2(g)4 NO(g) + 6 H2O(g) If only 2.00 g of NO were formed, what is the percentage yield for this reaction?
